To all whom it may concern.-

Be it known that I, ORRIN J. DAVY, a citizen of the United States, residing at VVashington, in the District of Columbia, have invented certain new and useful Improvernents in Electric Tram Systems, of which the following is a specification.

This invention has relation to electric tram systems; and it consists in the novel construction and arrangement of its parts as hereinafter shown and described.

The system is especially adapted for elevated, roads; but it may be used to advantage upon surface and subway roads.

The object of-the invention is to provide a v system of the characterindicated, which is so arranged that the motors, cars, or trains, as the case may be, are operated with safety and despatch, and with the exercise of a minimum amount of care and hcadwork on the part '1 the operators. Mechanical means is provided which in a great measure will relieve the operator of the necessity of exercising forethought and discretion in the proper o crating ofthe apparatus in his charge, t ereby leaving his faculties free of mechanical detail and keeping them in re serve in case of exigency, emergency. or sudden or unexpected occurrences or conditions calling for immediate action and attention should such arise. The value of such arrangements is keenly appreciated by those in management where life and property is at stake and placed in the hands of subordinates, and the infallibility of mechanical appliances is far more desirable than the exercise of manual discretion, prompted in many instances by the fallible mind. Inother words, the present system is designed to relieve its operators of much of the mental strain otherwise imposed upon them.

With these objects in view the system comprises a track orroad-bed upon which cars, carriers, or trains are arranged to 11m, and which are propelled by electricity. The seat of the operator is in a great measure the controlling and safety element of the moving body or bodies. The seat is provided with a swinging back, which, as a'mattcr of course, must be swung in the direction opposite to that in which the body is moving or is to .move in order that the operator may occupy the same. Such movement of the back of the seat automatically reverses the trolleyarm, which is connected with the seat back in such manner that such manipulation'may be accomplished. Also the controller is automaticall reversed by the swinging of the seat-bee always be moved in the same direction with relation to the seat to cause the moving body to travel in the direction. opposite to the inclination of the back of the seat. At the same time the swinging back automatically operates a reversing-switch or pole-changer in order that the electric currentmay be sent through the motor or motors in such direction as to cause the armaturcs thereof torotate, whereby the moving body will travel in the direction opposite to that of the incline tion of the seat-back. Means is provided for regulating the rate of speed of travel of the moving body, and safety-brake appliances are also located adjacent the seat and are adapted to be operated in a similar manner irrespective of the position of the seat-back. It will therefore appear that the operator at all times uses the appliances at his command i in the same manner to cause the moving body to travel forward and in the same manner to cause the said body to stop and back. Therefore there is no possibility of his becoming confused at critical moments, and at the same time the appliances so simplify an otherwise complicated system that a novice or unskilled person may with the greatest degree of safety manipulate and operate the same, all of which results in a saving of time, labor, anxiety, and damage.

In the accompanying rawings, Figure 1 is a side elevation of a carrier mounted upon the tramway. Fig. 2 is a to plan view of the same. Fig. 3 is an end ellivation of the carrier, showing the track in transverse section. Fig. 4 is a si e elevation of one end of the scat. Fig. 5 is a side e evation of the opposite end of the scat.

the currents when passing through the armatures of the motors in one direction; and Fig. 13 is a diagrammatic view of the wiring of a carrier, illustrating the course taken by the currents when' passing through the arma- 'tures of the motors in the opposite direction.

As illustrated in the accompanying drawings, the tramway comprises a track I, mounted upon the substantially A-shaped uprights 2, at' an interme iate point of each leg of which is located a side bearing-rail 3. Each upright is provided with suitable intermeniate bracing 4. The rail or track 1 may be of any desiroi'or approved pattern or configuration. The cross-arm 5 extends laterally from the upper portion of each upright and is provided with a hanger 6. The saiJ hangers throughout the system support the trolley-wire] in substantial parallel relation with the track 1, it of course being un erstood that the said trolley-wire support is at some convenient point provi ed with insulation which electrically separates the sai l trolley-wire from the track 1 tlLfi the upri hts 2.

Each carrier comprises a frame 8, aving journalod at its opposite ends the shafts 9 9. A traction-wheel 10 is mounted u on eachv shaft 9. The said traction-whee s travel upon the track 1. The motors 11 11 are supported. in part by the frame 8 and the shafts 9. The said motors are locate E at diagonal opposite corners of the frame 8 and serve to The armatureshafts 12 of the motors are priivi'ezl with gear-wheels 13, which mesh with the ear wheels l4,locate1i upon the shafts 9'. ltach shaft 9is provi ed with a r isk 15, around which passes a ban-l 16. The ro 's 17 con ncct the on s of saicl ban s with the brakelevers 18. Thus speed-checking mechanism is provi ed. The seat 19 is located upon the frame 8 and is provi ed with aback 20,which is pivoted at the points 21 to the enrls of the sail seat 19. The trolley-arm 22 is pivoted to the hanger 23, which (open s from the frame 8. The lower endv of said trolley-arm is provi ed with a trolley-wheel 24, which runs against the un l'er side of the currentwire 7. The pivotal point of the trolley-arm 22 is in vertical alinemcnt with one of the pivots 21 of the seat-back 20. The coil-spring 25 is attached at one en 1 to the seat-back 2U anl at its othenend to the trolley-arm 22, the points of attachment of the said coilspring with the seat-back an the trolley-arm being at opposite si' cs of the pivot of the said pivoted members. The upper end of the trolley-arm 22 is hollow, and. the pin 26 is slitfalrly located therein. Sal l pin is provided with the laterally-extending lugs 27 27, which arc located in the elongated slots 28, cut in the sides of the trolley-arm 22 and whichlimit the sli ing movement of the pin 26. The coil-spring 29 is located within the trolley-arm 22 and bears at its lower end against the bottom of the hollow provided in the upper end of the said arm and bears at its up er end against the lower end of the pin 26. tension of the said spring is such as to have a tendency to maintain t e upper end of the said pin projected. as far as possible beyond. the upper end of the trolley-arm 22 The lower end of one side of the seat-back 20 is provided with the gear-segment 30, the teeth of which are are ted to engage the upper end of the pin 26. he controller-post is coated upon the. frame 8 at the opposite end of the seat 19. The cont'roller lever casing 32 is retatably supported at the upper end of the post 31 and is provided atits hase with the external gear-teeth 33. The wire cable 34 passes up through the post 31 and enters the casing 32, where the wires are separated and are attached to the points 35, as illustrated in Fig. 10 of the erawin'gs. The controllerlever 36 is pivoted in the casing 32 and projects above the upper end thereof. The said controller-lever 36 is rovi. .ed with the usual contact-finger 37, which is adapted to engage the points 35. The plate 38 is pivoted upon one of the pivots 21 of the seat-back ZO ano is provi e1. with an elongated areuate slot 39. The side of the seat-back 20 is provided with a pin 49, which enters the sail. slot .39. The upper ortion of the plate 38 is provided with a tort ed. rack 4l,'which meshes 'with the gear 3 of the casing 32. The pole-chan ing switc 1 42 is located un i'er the seat 19. he pole-changing lever 43 passes through the seat 19 and. has its upper end located in the path of the lower (H.510 of the seat-back 20. The sail pole-changing. lever 43 is arranged to swing in asherter are than the seat-back 20.

From the foregoing description it is obvious that when the seat-back 20 is swung on its pivots 21 the teeth of the gear segment will engage the end -of the pin 26 andcau'se the trolley-arm 22 to swin on its pivot against the tension of the spring 25. At the same time the spring 29, hearing against the lower end of the pin 26, will permit the? said pin 26 to move longitudinally with the end of the trolley-arm 22 to compensate for the diflerent arcs described by the segment 30 and the trolley-arm 22 in swinging, and thus the seat-back 29 and the trolley-arm 22 are swung simultaneously and are at all times lying in the same general direction with relation to the seat 19-that is to say, when the carrier is going in one direction the seat-back 20 and trolley-arm. 22 will be inclined in the opposite direction with relation to the seat 19. At the same time that the seat-hack 20 is swung the pin will move until eventually it will engage the end of the slot 39 of the plate 38, when the said plates will also swing upon the pivot. 21, to which it is attachcd and tho gear-tecth 41 thereof, engaging the gear-teeth 33 of the casing 32,will cause the said casing to describe a half-rota- KOO IIS

tion, which in turn will turn the controllerlcver 36. Thus the position of the controller-lever 36 is always the same as that of the seat-back 20 with relation to the seat 1.9, and in order to start the carrier the said controller-lever 36 is always moved in the same di l'ection with relation to the seat, and in order to stop the car is moved in the opposite direction with relation to the seat. At the same time that the seat-back 20 is swun the lower edge thereof enga es the end the pole-changing lever 43 an operates the same to send the current through the armatures of the motors in the opposite direction, as will be hereinafter explained. By reason ofthe fact that the lower edge of the seat 2Q de- Scribes a different arc from the upper end of the pole-changing lever 43 the seat-back will escape the upper end of the pole-changing lever 43 when the latter has reached the limit of its movement. provided, such as a spring, for causing the said pole-changing lever to move slightly in the reverse direction after it has been escaped by the seat-back 20 in order to bring the upper end of the same within the path of the said seat-back, so that it may be engaged by the seat-hack when swung in the reverse di rection. It will thus be seen that the corn troller-lever, the pole-changing lever, and the trolley-arm are at all times inclined in the same general direction with relation to the seat, and consequently the maniphlation of such parts as are intended to be operated manually are accomplished in the same way irrespective of the direction in which the carrier is traveling. Thus the possibilities of confusing the operator are reduced to a minimum. The hangers 44 depend from the frame 8 and are provided with the rollers 45, which bear against the side rail 3. The said hangers are also provided wit i seats 46 or other receptacles for carrying a load.

Tie wiring of tlie carrier is as follows: Tire Wire 47 extends from tile trolley-wheel 24 to tie controller-lever 36. The wire 48 is connected at one end with the points 35 and joins with tie wire 49. Said wire 49 joins with tlre wire 50, which connects with the field 51 of tie motor A. The wire 52 connects tlce field 51 with. the point 53, located in the pole-cl anger 42. The wire 54 connects tl'e point 53 with the point 55. The brush 56 is located in the path of tie point 55, and tite wire 57 is connected at one end to t e brush 5.6 and at its ot er end to one of tle brushes of tie armature of tie motor A.

Tlie opposite brush of ti c said armature is connected by the wire 58 with the brush 59. Ti c said brush 59 is located in the path of tie point 60 and tie point 53. The wire 61 connects the point 60 with the point 62, and ti e Wire 63 connects the point 62 with the ground, wl ich in tl'e present instance is do frame 8. The brush 56 is also located in the path of the Means, however, is Q point 62. The wire 64 connects the wire 50 with the field 65 of the motor A. Tlie wire 66 connects tlie field 65 with tlte wire 52. The wire 67 connects the wire 48 with the wire 68. Said wire 68 connects with the field 69 of the motor B. The wire 70 connects the field 69 with the point 71 of the pole-changer 4.2. The wire 72 connects the oint 71 with the point 73. The brush 74 is coated in the path of the oint 73, and the wire 75 connects-said brus with one of the brushes of the armature of the motor B. The wire 76 connects the opposite brush of the motor B with the brush 7 7. The oints 78 and 71 are located in the path of t e brush 77. The wire 79 connects the oint 78 with the point 80. The brush 7 4 is coated in the path of the points 80 and 73. The wire 81 connects the point 80 with the point 60. The wire 82 connects the wire 67 wlth the field 83 of the motor B, and the wire 84 connects the field 83 with the Wire 70. At the end of the stroke of the controller-lever 36 the contactfinger 37 will span from the end point 35 and rest upon the point 85. The wire 8600mnects the point 85 and joins with the wire 87. The said wire 87 connects with the field 51 so as to cut out part of the said field-winding. Tlie wire 88 connects the wire 87 with the field 65, so as to cut out part of the winding of the said field. The wire 89 connects the wire 86 with the wire 90. The wire 90 connects with the field 69, so as to cut out part of the winding thereof. The wire 91 connects the wire 89 with the field 83, so as to cut out part of the winding tl. ereof.

The course of the current through th motors A and B is as follows: Assume that the points 62, 53, 55, 60, 80, 71, 78, and 73 are in the position as shown in Fig. 12 of the drawin s that isto say, brush 77 is in contact wit lpoint 71, brush 74 is in contact with point 80, brush 59 is in contact with point 53, and brush 56 is in contact with point 62. When the contact finger 37 of the controller-lever 36 is moved into engage.- ment with any one of the points 35, the current comes from the wire 7 through trolle wheel 24 and wire 47 to the lever 36, through the contact-finger 37 of lver 36 to oint 35, thence along wire 48 to wire 49, a ong wire 49 to wire 50, along wire.50 to field 51 of motor A, along wire 52 to point 53 of the pole-chan er 42, along lgrush 59 to wire 58, through tiie armature 11 of motor A, thence along wire 57 to brush 56, thence to point 62, thence along wire 63 to the ground, which in the present instance is the frame 8 of the carrier. From the wire 50 the current also passes along the wire 64 to the field 65 of motor A, t ence along wire 66 to wire 52, where it joins with the current passing along the said wire from the field 51. At the same time the current passes from wire--43 along the wire 67 to wire 68, thence along wire 68 B, thence through the said field and along be brought in contact with the brush, 56. l

to field 69 of motor B, thence along wire to point 71 of the pole-changer 42, thence along brush 77 to wire 76, thence along sald wire 76 to one of the brushes of the armaturell of motor B, thence through the said armature to the opposite brush thereof, thence along wire to brush 74, thence to point of the pole changer 42, thence along wire 81 to point .60, thence along wire 61 to point 62, and thence along wire 63 to ground 8. At the Elaine time the current will pass from wire 67 along wire 82 to the field 83 of thenrotor the wire 84 to the wire 70, where it joins with the current coming from the. field 69 of the said motor. Thus the electric current is sent throu h the armatures 1.1 of the motors A and in one direction.- When the lever 36 is moved to the forward end of its stroke, the contact-finger 37 will spanthe end point 35' and the oint 85. Thus, in addition the courses a ove described, the current will also-pass from the point along the wire 86 to wire 87, thence along wire 87 to the field 51 of the motor A. he said wire 87 con nects with the f'eld 51, so as to cut out a portion of the winding thereof. time the current will 'pass from the wire 87 alon the wire 88 to the field 65 of the motor A. Ihe said wire 88 also connects with the field 65 in order to cutout aportion of the winding thereof. At the same time the current will pass from the wire 86 along the wire 89 to wire 90, thence-along said wire to the field 69 of the motor B. At the same time the current will pass from the wire 89. along the wire 9] to {he field 83 of the motor B. The wires and 9] connect with the fields 69 and '83, so as to cutout portions of the windings thereof. Thus when the cohtroller-lever 36 is moved to the forwardcnd of its stroke the current will follow the line of least resistance, and instead of passing down wire 48 and through all the'windi'ngs of each motor-field it will pass down wire 86 and through only a small portion of the wind} ing of each field. This reduced current is sullieient ,to keep the motors going aftenthe same have been speded-up to maximum,

and i the current 'is accordingly shunted through the motor-fields in the manner described as a matter of econoi'ny. V

When the seat-back 2U isswuug in the opposite direction, the edge of the said seat will engage the pole-changer lever 43 in the n1anners above described and turn the same so that the oint 87 of the polo-changer 42 will be brou it in contact with the brush 77, the

oint 7. will bebrought in contact with the rush 74, the mint 60 will be brought in con.- tac't with the rush 59,-anrl the point 55 will The partsswill then be in the position as illustratedfih Fig. 13 of the drawings.. Thus whenthe controller-lever 36 is moved so i At the same- 7 -=63 to the ground 8.

.motor B.

that the contact-finger 37 thereof engages anyone of the points 35 the current will pass 'from the wire47 through the contact-finger 56 to 'wire 57, thence along said wire to one of the brushes of the armature 11 of the motor A, thence through said armature to the opposite brush of the same, thence along wire 58 to the brush 59 of the pole-changer 42-,

I thence to point '60, thence along wire.61 to point 62, thence along wire 63 to ground 8. At the same time the current will pass from wire 49 along wire 64 to the held 65 of the motor A, thence along wire 66 to the wire 52. At the same time the current will pass from the wire 48 along the ,wire 67 to wire 68, thence along said wire tothe field 69 of the motor B, thence through said field and along wire 70 to the point 71 oi the ole-changer 42, thence along wire 72 to tiepoint 73,-, thence through brush 74 and along wire.75'to one of the brushes of the armature ll of the motor B, thence tlu'ough said armature and the opposite brush thereof to w ire 76, thence along wire 76 to brush 77, thence to point 78, thence along wire 79 to point 80, thence along wire 81 to point 60, thence along wire 61 to point 62, and thencealong wire current will pass from the wire 67 along wire 82 tothe'field 83 of the motor B, and

At the same time the thence through the said motor andfalong tlrewire 84 to the wire 70, where it joinsthe current passing along the last said wire.

'Whcn tlrc controller-lever36 has been moved to the forward, end of its stroke, the current -wi'll also pass through the finger 37 to point '85, thence, along wire 86 to wire 87, thence along said wire to the field 51. At the same time the current will pass from wire '87 along the wire 88 to the field 65 of the motor At the same time the-current will pass from the wire 86 along thewire 89 to wire thence along the, wire 90 to the field 69 of i he '7 At the'same time the current will pass from the wire 89 along thewire 91 to the lield83 of the last said motor. As. the wires 50, S8, 69,. and QLconnect'with the fields oi the motors, as above described, the current is shunted through the windings of the said mo tors. In the description of the passage of the current as illustrated in Fig. 13 it will be observed thatvthe current passes through the armatures 1 1 l1 ofthe motors A and Binthe opposite direction from 'the course taken b the current as shown and described for the diagramrriatic view illustrated in Fig. 12 of the drawings. Thus the reversing of the mo-' tors is'accornplished by the swinging of the seat-back 20;
